PHONOGRAPH RECORD AND METHOD OF MAKING THE sum.

Application fled April 82, 1926- Serial I0. 103,758.

My invention relates to improvements in phonograph records of the disktype and has for one of its objects a raised outer run which has a.commercial advantage in that the needle, if placed upon the smoothsurface of the rim when starting to play the record, will automaticallyrun down said smooth surface and enter the record groove.

Another object of my inventlon 1s to prol0 vide a disk type phono raphrecord with a raised outer rim whic will prevent the threads of thespiral record groove from becoming marred when they are placed upon oneanother.

Another object of my invention is to provide a knurled edge upon theouter periphery of the record which affords a firmer grip when removinthe record from the phonograph turn ta le or when takin it out of therecord compartment of the p onograph cabinet.

Duringthe process of manufactur ng my improved disk record, the fin,WlllCl'l 1s ordinarily present on records when taken from 26 the presseshas been replaced by the knurled edge. This elimination of the finresults in economies of manufacture because the ed ing rocess requiredto remove it results in breakage and marring of records, and also 30permits the records to be moved directly from the presses to theinspectlon department. The absence of the fin also makes it possible toaccurately determine the weight of the record so that the correct amountof material required to form it can be injected into the dies,eliminating the ossibility of producing underweight recor s which areeasily broken in transit or handling, or the production of overweightrecords which represent a loss in material. Y

With these and other objects in view, to be more fully set forthhereinafter, the invention consists in the novel construction,combination of elements and arrangement of parts which will beexemplified in the construction herein described in the followingspecification and illustrated in the accompanying drawings.

The invention will first be described in connection with theaccompanying drawings, wherein similar reference characters are used todesignate corresponding parts throughout the several views, and morespecifically defined and indicated in the appended claims.

Attention is directed to t e drawings in which:

Fig. 1 is a partial proved disk record;

Fig. 2 is a sectional view of same looking in the direction of thearrows 2-2;

Fig. 3 is an enlarged partial sectional view illustrating the raised rimand lmurled edge;

Fig. 4 is an enlarged view illustrating a portion of the knurled edge;and

Fig. 5 is an enlarged partial sectional view illustrating how the recordgrooves are prevented from becoming marred when placed upon one another.

Referring tothe drawings, numeral 1 re resents the record, 2 the usualhole in t e center of the record for centering it upon the turn-table ofthe phonograph, and 3 the usual spiral record groove. The edge or rim 4is of greater thickness than that portion of the record into which therecord groove is pressed; its smooth surfaces or faces, starting at thebeginning of the record groove, diverging outward at a slight angle tothe periphery as illustrated in Figs. 2, 3 and 6. A reproducer partiallyrepresented by dot and dash lines, when placed upon the highest point ofthe rim as illustrated at R, will take the position illustrated R whenthe record starts to revolve. This inward swing causes the needle toenter the groove immediately, thereby eliminating the usual numerousattempts to find the groove, and making it possible to start playing myimproved record in total darkness. The rim 4 also protects the, recordgroove from becoming marred. This is due to the thickness of the rimwhich prevents the record grooves from coming into contact with eachother or with a table top when placed upon it as illustrated in Fig. 6.The knurled edge 5 of the rim 4 afiords several advantages which are asfollows: First, it can be easily picked up when lying upon a flatsurface, the particular formation of the knurling allowing the finger Fof the operator to et a firmer grip as illustrated in Fi 3. be secondadvantage of the knurled edge is that it eliminates the usual fin whichforms upon the record when it is molded, the excess material being takenup in the knurling.

In accordance with the provisions of the plan view of my impatentstatute, I have described my invention, but I desire it understood thatmy invention is not confined to the particular form shown and described,the same being merely illustrative, and that the invent1on can becarried out in other ways without departing from the spirit of minvention, and therefore, I claim broadly t e r1 ht to emloy allequivalent instruments ities commg within the scope of the appendedclaims, and by means of which, ob ects of my invention are attained, andnew results accomplished; as it is obvious that the particularembodiments herein shown and descrlbed are only some of many that can beem loyed to attain these objects and accomplish these results.

\Vhat I claim and desire to obtain by Letters Patent is v 1. Aphonograph record of the character described having an enlarged IlIIlwith a knurled transverse edge.

2. A phonograph record of the character described having a rim ofgreater thickness than that portion of said record into wh ch the recordgroove is pressed said rim having a knurled transverse edge.

3. A phonograph record of the character described having an enlarged rimw1th a knurled transverse edge, the faces of said rim starting at thebeginning of the record groove.

4. A phonograph record of the character described having a rim with aknurled transverse edge and of greater thickness than that ortion of therecord into which the record groove is pressed, the faces of said rimstarting at the beginning of the record groove.

5. The method of making a disk sound record consisting in knurling theedge of the record during the operation of forming a sound groove in therecord body.

6. The method of making a disk sound record consisting in knurling thetransverse edge of the record.

7. The method of making a disk sound record consisting in knurlingthetransverse edge of the record during the operation of forming a soundgroove in the record.

8. As a new article of manufacture, a disk sound record having itstransverse edge knurled.

9. A ste in the manufacture of making a disk soun record consisting inressing a design into the edge of the record body.

10. The method of finishing the edge of a disk sound record consistingin molding a design in said edge.

11. As a new article of manufacture, a disk sound record having a designformed in its transverse peripheral edge.
